Vertebrate fauna genesis in the Middle Paleozoic Podolian paleobasin
The formation of the Early Devonian ichthyofauna occurred under the combined influence of
historical, paleogeographic and paleoecological factors. A consequence of evolutionary development at
the beginning of the Devonian period arose a number of high-ranking taxa of sea vertebrates, which
actively colonized the shallow water basins of new continent Laurussia. For representatives of local
endemic faunas there was an opportunity to expand their habitats. There were exchanges of migrants
between neighboring regional faunas. All this was accompanied by the evolution of ecosystems, the
formation and development of new ecological niches. Early Devonian for most groups of vertebrates was
marked by a sharp increase in the number of taxonomic units. The formation of Podillya regional
ichthyofauna illustrates these trends of global biotic changes in that time.
Key words: ichthyofauna, faunogenesis, paleogeography, paleoecology, Early Devonian, Podillya.
